The Galaxy S7 was designed to be premium, and Samsung clearly accomplished its goal. The South Koreans used only metal or glass for an overall appearance that looks exquisite(glass is on both the front and the back, and metal was used for the surrounding frame).
There’s absolutely no plastic on the phone, and the attention to detail is impressive, to say the least. The side buttons are made of metal too, and while the bottom part looks very similar to the S6, which in turn seems to be inspired from the iPhone, it definitely contributes to the premium feel and perfectly blends into the overall design.
As compared to the S6 lineup, the Edge models are now bigger, as the previous versions came with a 5.1-inch screen while this one now has a display of 5.5 inches. This doesn’t necessarily mean that it’s much bigger, as Samsung spent a lot of time redesigning the bezels.
The Edge has almost no side bezels, which becomes more obvious when you unlock the screen. If you keep it turned off, the black screen matches the black case, and you can barely notice the display margins, so everything blends quite nicely here too. When putting the Edge and the iPhone 6s Plus side by side, Apple’s model looks huge and ugly, especially when viewed from the back. The Edge is much easier to carry in the pocket, as it’s a lot smaller than the iPhone despite having the same screen size.
The Galaxy S7 Edge is available in two different CPU configurations, depending on the market. Buyers in the United States receive the Snapdragon 820 processor while Europeans(this is also known as international version) get the Exynos 8890 Octa version. They provide similar capabilities, but the Exynos is said to be further optimized for longer battery life. The Snapdragon, on the other hand, is 32 percent faster when it comes to graphics processing power.
Both processors, however, are based on the 14nm FinFET chip, which is currently the smallest available, but the Exynos uses slightly different technology. The big.LITTLE architecture that Samsung employs has two different sets of quad-core CPUs that it uses only when needed - all are brought into play when maximum processing power is required, such as when editing a 4K video.
The Exynos uses four M1 cores, which were specifically optimized for speed and battery life. Benchmarks have shown that they’re 30 percent faster than the Exynos 7 siblings used before.
Also depending on the version you choose, the S7 Edge is available in two different GPU variants: Adreno 530 and Mali-T880 MP12, both worthy upgrades over the Mali-T760MP8 used on the Samsung Galaxy S6 Edge+.
